Some thoughts on the 12 350-only subjects that have been seen with OM but not EPDG:
1. Of the 12, three, namely, Brown (Wash.), Dahlen (Brooklyn), Elberfeld (Wash. Portrait), are really bifurcated 150/350 subjects that experienced the 350 portion of the 150/350 print run, their predecessors G. Brown (Chicago), Dahlen (Boston) and Elberfeld (N.Y.) having undergone the 150 portion of the 150/350 print run. Moreover, Dahlen (Boston) and Elberfeld (N.Y.) were even extended nominally into the 350 portion before being replaced by their successors Dahlen (Brooklyn) and Elberfeld (Wash. Portrait). Accordingly, we know that these "three amigos" Brown (Wash.), Dahlen (Brooklyn) and Elberfeld (Wash. Portrait) were not introduced until the END of the 350 portion of the 150/350 print run.
2. Meanwhile, the EPDG print occurred at the BEGINNING of the 350 portion of the 150/350 print run. We know this because Ted has identified the "elite eight" 150/350 subjects that were removed from print before the other 150/350 subjects and appear with only two 350 series backs--Piedmont 350 and EPDG (and in very small quantities with these backs).
3. Based on 1 and 2, it is unsurprising that these "three amigos" appear with OM but not with EPDG. Indeed, it would be surprising if the situation were otherwise.
4. I cannot explain why there are nine other 350-only subjects that appear with OM but not EPDG. Could it be that time will reveal these nine subjects with EPDG, or that they were printed with EPDG but all examples have been lost to time?
